BACKGROUND

The present disclosure relates generally to structures for storing items such as equipment, materials and/or people. More particularly, the present disclosure relates to a structure that can be moved to a construction site and can be secured for storing items therein.

Many construction sites such as pipelines, highways, power transmission lines, etc. are linear in nature. Such construction projects can be very remote and may require numerous pieces of large industrial equipment. One problem encountered by contractors and developers of such projects involves on-site management of equipment. The equipment and supplies that the contractor uses to complete the project are usually very expensive. Logistical considerations require such contractors and developers to store supplies and equipment on-site where it is convenient and can be accessed on demand during the project. As a job progresses, a storage site can be intermittently moved to new locations corresponding to the progress of construction such that the equipment and materials are located near the position they are needed the most.

Conventional practices typically involve storing equipment and materials on-site at jobsite locations during periods of non-use in storage containers. Such conventional storage containers can include the type of containers used in transoceanic shipping. Conventional job-site storage containers can include a metal frame having corrugated panels and one or more hinged doors for accessing the interior of the container. A mechanical lock is commonly attached to the doors for securing the contents inside. Such containers can be picked up using a crane or a large truck and can be transported along the development path of the project.

This type of conventional jobsite storage container, however, is susceptible to break-in using hammers, bolt cutters, blow torches or other readily available tools. As a result, contractors and developers are often reluctant to store expensive items in such conventional containers during periods of non-use.

Another alternative available to contractors and developers for protecting expensive equipment stored on-site is to hire security personnel to monitor such storage containers during periods of non-use of the stored equipment. However, this option is prohibitively expensive in most applications, particularly in long duration projects.

The concern of theft of expensive equipment and potential delays in workflow creates significant problems for contractors and developers who logistically need to store equipment on-site. Because of these problems with conventional storage systems, man contractors essentially mobilize and de-mobilize project sites on a daily basis.

An additional problem associated with storing materials at such worksites is the storage of fuel. Fuel is commonly necessary for operating equipment. However, fuel tanks are often subject to theft or vandalism when left on-site during periods of non-use. Additionally, firearm users frequently shoot at fuel tanks left at construction sites, thereby damaging or ruining the fuel storage containers. Spilled fuel can lead to pollution and environmental cleanup concerns that can be extremely expensive to remedy. This places a significant burden on contractors who are oftentimes responsible for paying for pollution cleanup when fuel is leaked.

What is needed then is an improved storage facility for securely housing items at jobsite locations.

Referring now to the drawings, one embodiment of the present disclosure provides a storage apparatus, illustrated generally in FIG. 1 and designated by the numeral 100. It is understood that in the drawings, not all reference numbers are included in each drawing, for the sake of clarity. In addition, positional terms such as a “upper,” “lower,” “side,” “top,” “bottom,” “vertical,” “horizontal,” etc. refer to the apparatus when in the orientation shown in the drawing. The skilled artisan will recognize that objects in accordance with the present disclosure can assume different orientations when in use. The drawings illustrate various embodiments and are not intended to provide dimensional or scale limitations on the claims. It is understood that various other embodiments can include numerous scale and dimensional characteristics that are not illustrated.

Referring to FIG. 1, a storage apparatus 100 includes a top panel 134, a first side panel 138 a, a second side panel 138 b, and a bottom panel 152. The terms “panel” and “wall” may be used interchangeably to describe the components of storage apparatus 100. Top panel 134 is generally supported by the first and second side panels 138 a, 138 b. An end panel 140 is disposed at one longitudinal end of the storage apparatus 100. As such, the storage apparatus 100 forms an enclosed structure housing an interior space for storing items.

A door assembly is disposed on the storage apparatus 100 at the longitudinal end opposite end panel 140. The door assembly 112 includes a vertically sliding outer door panel 116 and a fixed interior door panel 118. FIG. 11A illustrates an outer door panel 116 including first and second door lift anchors 146 a, 146 b.

Outer door panel 116 includes a pre-stressed concrete slab door that is generally configured to be vertically moveable. Outer door panel 116 includes a first door panel vertical edge 108 and a second door panel vertical edge 110.

Interior door panel 118 includes welded wire fabric (WWF) in some embodiments. Referring to FIG. 12A, in some embodiments, interior door panel 118 includes first and second cage supports 126 a, 126 b. Each of first and second cage supports 126 a, 126 b are configured to be fixed in place in the entry to apparatus 100. A first entry door 136 a is hingedly attached to first cage support 126 a, and a second entry door 136 b may be hingedly attached to second cage support 126 b. Access to the interior of the storage apparatus 100 is through the end of the unit containing door assembly. Each entry door 136 a, 136 b can include a separate security system such as an additional lock or code-access feature for further controlling access to storage facility 100. In some embodiments, each entry door and each cage support includes a single layer or a double layer wire mesh, or wire fabric mounted on a rigid steel perimeter frame. In some embodiments, only a single entry door 136 is positioned behind outer door panel 116. Outer door panel 116 can be selectively raised vertically such that entry door 136 can be used to access the interior of storage facility 100. When outer door panel 116 is in the closed position, as seen in FIG. 1, access to entry door 136 is blocked. When outer door panel 116 is in a raised, or partially raised, position, as seen in FIG. 2B, entry door 136 is accessible.

In some embodiments, top panel 134, side panels 138 a, 138 b, end panel 140, and outer door panel 116 in some embodiments are formed of concrete. Outer door panel 116 can include a pre-stressed concrete material. In some embodiments, outer door panel 116 includes pre-stressed concrete reinforced with steel fibers such as but not limited to Novocon® 1050 steel fibers manufactured by Propex Concrete Systems of Chattanooga, Tenn. In other embodiments, other types of steel fibers having similar properties can be used to reinforce outer door panel 116. Additionally, each concrete panel disposed on facility 100 can include similar reinforcing steel fibers. Steel fiber reinforcement of concrete panels provides additional resistance to penetration by tools that could be used to break into the storage apparatus 100, such as hammers, chisels, prybars, drills, etc.

In some embodiments, each panel in apparatus 100 includes concrete at 5000 psi and includes steel reinforcement fibers. Reinforcement fibers are grade 60 in some embodiments. In addition, pre-stressing strands may be held in tension in each panel. In some embodiments, each panel is pre-stressed with one or more pre-stressing strands including non-coated, one-half inch seven-wire at 270 kpi. In various other embodiments, other types of pre-stressing strands may be used in pre-stressed concrete panels in apparatus 100, including but not limited to pre-tensioned and post-tensioned strands in bonded or un-bonded configurations.

Each of the panels can be joined together prior to positioning at a construction site. For example, storage apparatus 100 can be pre-assembled and shipped in a pre-assembled state to a remote construction site as a complete unit. Alternatively, storage apparatus 100 may be assembled on-site at a construction location in some applications. In some embodiments, one or more panels on storage apparatus 100 may be joined by welding. In other embodiments, other suitable concrete panel joining techniques may be used to join the separate panels of storage apparatus 100.

Referring now to FIGS. 2A-3B, in some embodiments, a door assembly includes a novel construction for providing a sliding joint between outer door panel 116 and storage apparatus 100. Storage apparatus 100 can include a first side wall 138 a forming a first panel flange, or first side flange 120 a protruding from a first vertical edge 104 of first side wall 138 a. In some embodiments, first panel flange 120 a extends substantially perpendicular to first side wall 138 a. Similarly, second side wall 138 b includes a second panel flange, or second side flange 120 b protruding from a second vertical edge 106 of second side wall 138 b generally toward first side flange 120 a. First and second panel flanges 120 a, 120 b can include a reinforced pre-stressed concrete or any other suitable rigid material such as metal. In some embodiments, first panel flange 120 a is integrally formed on first side wall 138 a and second panel flange 120 b is integrally formed on second side wall 138 b. Each panel flange 120 a, 120 b can form a right angle relative to its corresponding side wall in some embodiments.

As seen in FIG. 6, a metal plate 122 can be disposed on each side wall 138 near a flange 120 in some embodiments. As seen in FIG. 10B, metal plate 122 may extend almost the entire height of each side panel 138. Metal plate 122 in some embodiments includes a steel plate embedded in the side panel 138. Metal plate 122 can include an embedded steel plate with dimensions of about two inches wide by about eight feet four inches tall by about five sixteenth of an inch thick in some embodiments. In other embodiments, each metal plate 122 may include various other suitable dimensions. Metal plate 122 can be cast into concrete side wall 138, as seen in FIG. 6. In some embodiments, a first metal plate 122 a is embedded in first side wall 138 a, and a second metal plate 122 b is embedded in second side wall 138 b.

A metal angle bracket 124, or door guide, can be secured to metal plate 122. Metal angle bracket 124 can be welded to a metal plate 122 in some embodiments. In other embodiments, each metal angle bracket 124 may be secured to a corresponding metal plate 122 using other suitable fastening means, such as using fasteners. Each metal angle bracket 124 includes a bracket flange 125 protruding away from metal plate 122. Bracket flange 125 is oriented generally parallel to its neighboring side flange, or panel flange 120. As such, each panel flange 120 and bracket flange 125 define a flange gap 128 therebetween. Flange gap 128 is generally slightly larger than the thickness of outer door panel 116 such that a vertical edge of outer door panel 116 can be slidably received in flange gap 128. In some embodiments, a clearance of about one-half inch is defined on each side of each vertical edge of outer door panel 116 for allowing outer door panel 116 to slide freely in flange gap 126. A first flange gap is formed on the first side of outer door panel 116 nearest first panel flange 120 a, and a second flange gap is formed on the opposite second side of outer door panel 116 nearest second panel flange 120 b.

Referring further to FIG. 4A and to FIG. 6, in some embodiments, interior door panel 118 spans across the entry of door assembly and can be secured at opposing edges generally to first and second side panels 138 a, 138 b. In some embodiments, interior door panel 118 can be secured by welding or fastening to each angle bracket 124 on each side panel. For example, a first vertical edge of interior door panel can be secured to a first angle bracket attached to first side panel 138 a, and the opposing second vertical edge of interior door panel can be secured to a second angle bracket attached to second side panel 138 b. In some embodiments, interior door panel 118 is welded to the bracket flange 125 on each angle bracket 124. In other embodiments, interior door panel 118 may be welded to various other features on each angle bracket 124, or alternatively to each metal plate 122.

In some applications, it may be desirable to mechanically fix, or anchor, outer door panel 116 in an open position to prevent outer door panel 116 from inadvertently falling. To achieve this, one or more door pin sockets 172 a, 172 b can be formed on outer door panel 116. Each door pin socket 172 a, 172 b can be shaped to receive an anchor pin, 130 a, 130 b, as seen in FIG. 1. When the outer door panel 116 is in an open position as seen in FIG. 3B, each door pin socket 172 a, 172 b is aligned with a corresponding flange pin hole 142 a, 142 b defined in a side flange 120 a, 120 b, seen in FIG. 1. Each flange pin hole 142 a, 142 b in some embodiments, includes a five-eighths inch through hole defined through its corresponding flange 120 a, 120 b. An anchor pin 130 a, 130 b can be inserted through the flange pin hole 142 a, 142 b and also through a corresponding door pin socket 172 a, 172 b such that each anchor pin 130 a, 130 b prevents outer door panel 116 from moving relative to storage facility 10. In some embodiments, a rigid pipe sleeve is disposed in each flange pin hole 142 a, 142 b to provide additional strength. In additional embodiments, each door pin socket can be positioned on door panel 116 to align with a corresponding flange pin hole when door panel 16 is in a closed position for securing door panel 116 in the closed position.

As seen in FIG. 2B and FIG. 3B, in some embodiments, outer door panel 116 can be raised and secured at a raised position by allowing one or both anchor pins 130 a, 130 b to engage lower door edge 137, seen in FIGS. 11B and 11C when each anchor pin is inserted in its corresponding pin hole 142 a, 142 b, etc. As such, each pin prevents outer door panel 116 from falling shut as a redundant safety feature in the event that the mechanical door lifting feature were to fail. As seen in FIGS. 11B and 11C, in some embodiments, lower door edge 127 includes a tapered profile.

Referring further to FIG. 2A, an electronic control device such as a keypad console 148 may be used to control access to the storage apparatus 100 in some embodiments. A user can enter a code on keypad console 148, and a mechanical lift positioned on storage apparatus 100 will mechanically lift the outer door panel 116 to an elevated position, as seen in FIG. 2B. An access code can be programmed on the keypad console 148, and the code can be changed by an administrator for security reasons. Outer door panel 116 can be equipped with a global positioning satellite (GPS) transceiver that can receive location data from a satellite and can transmit a location signal representative of the location of the outer door panel 116 in three-dimensional space. The location signal can be monitored from an on-site or off-site location such that unauthorized movement of outer door panel 116 will be detected via the location signal sent by the GPS transceiver in some embodiments. In some embodiments, the location signal is sent via a cellular communication network wirelessly to a cellular base station using a mobile electronic device. The GPS transceiver will also be able to detect movement of the entire storage apparatus 100.

In some applications an external keypad console 148 may be susceptible to vandalism or damage from the weather or working environment. Referring to FIG. 15, in some embodiments, a communications module 176 can be housed within storage apparatus 100. Communications module 176 can include a wireless transceiver receiver operable to receive a communication signal 174 emitted by an external wireless transmitter 178, or signal transceiver, from outside of storage apparatus 100. For example, a signal emitter or transceiver 178 can be positioned in a worker's automobile, similar to a garage door opener in some embodiments. Communications module 176 can be operably connected to a motor or electronic motor control circuitry for mechanically raising and/or lowering outer door panel 116 in some embodiments. Thus, a user can transmit a communication signal 174 remotely for raising door panel 116 without actually contacting storage apparatus 100. Additionally, communication module 176 can include a weather station for communicating or recording weather information in some embodiments. Additionally, because communication module 176 is housed within the interior of storage apparatus 100 in some embodiments, the electronics associated with opening outer door panel 116 are not exposed to the elements and are not susceptible to vandalism from the outside. In some embodiments, communication signal 174 is a radio frequency signal. In further embodiments, communication signal 174 can include other suitable types of wireless communication signals.
